18.07 would already qualify depending on one questionable interpretation: there's an A-B-B speed burst at the start that involves jumping off the starting floor and then landing back on that same floor. Once I break the plane of the forward edge of that floor, there is indeed no standing, but it is its own brief airborne section.

I have no qualms with allowing it because you could just as easily redo it without the A-B-B, super red is a little more interesting than the previous red emeralds/keys/muffins, while it still focuses on DESTROYING THINGS and/or Score, more on that later!

Super White completed (add this to the list of "you'll see it in my speedrun", that list is getting huge).Super Red -easily- done first try, I don't get why you guys were having trouble avoiding a ring, there's not one that's particularly tricky. :P

530 tries. The "no boosts" is an absurd, random, and very poorly thought out restriction. If you can pass the 59th car before the bottleneck, then you won't be in any time trouble, and if you can't pass it by then, there's nothing you can do except dig in behind it, which forces you to lose so much time that there's no shot at the 2:50.

The closest run-in is with car 13, right at the end of the lap 1 tunnel, but you can check that part to see and hear that there's no collision and the car stays intact behind me.

In summary: That's three straight challenges you clearly haven't thought out and tested sufficiently. I doubt you'll be running this much longer.
